Knee Pain

Most people have had a minor knee problem at one time or another. Most of the time our body movements do not cause problems, but it’s not surprising that symptoms develop from everyday wear and tear, overuse, or injury. Knee problems and injuries most often occur during sports or recreational activities, work-related tasks, or house work.

The knee is the largest joint in the body. The upper and lower bones of the knee are separated by two discs (menisci). The upper leg bone (femur) and the lower leg bones (tibia and fibula) are connected by ligamentstendons, and muscles. The surface of the bones inside the knee joint is covered by articular cartilage, which absorbs shock and provides a smooth, gliding surface for joint movement.

Knee Structure

Although a knee problem is often caused by an injury to one or more of these structures, it may have another cause. Some people are more likely to develop knee problems than others. Many jobs, sports and recreation activities, getting older, or having a disease such as osteoporosis or arthritis increase your chances of having problems with your knees.

Sudden (Acute) Knee Injuries

Knee Injuries are the most common cause of knee problems. Sudden (acute) injuries may be caused by a direct blow to the knee or from abnormal twisting, bending the knee, or falling on the knee. Pain, bruising, or swelling may be severe and develop within minutes of the injury. Nerves or blood vessels may be pinched or damaged during the injury. The knee or lower leg may feel numb, weak, or cold; tingle; or look pale or blue. Acute injuries include:

  • Sprains and strains
  • Meniscus Tear.
  • Tear at Anterior cruciate ligament (ACL) or medial collateral ligament (MCL).
  • Breaks (fracture) of the kneecap.
  • Kneecap dislocation. Pieces of bone or tissue (loose bodies) from a fracture or dislocation may get caught in the joint and interfere with movement.
  • Knee joint dislocation.

Overuse Knee Injuries

Overuse injuries occur with repetitive activities or repeated or prolonged pressure on the knee. Activities such as stair climbing, bicycle riding, jogging, or jumping stress joints and other tissues and can lead to irritation and inflammation. Overuse injuries include:

  • Knee bursitis.
  • Knee Tendinitis or Knee Tendinosis.
  • Plica syndrome.
  • Pain in the kneecap – patellofemoral pain syndrome.
  • Iliotibial band syndrome.

Conditions that may Cause Knee Problems

Problems not directly related to an injury or overuse may occur in or around the knee.

Treatment for Knee Pain

Treatment for a knee problem or injury may include:

  • Anti-inflammatories
  • Lubricant Injection
  • Physiotherapy
  • Surgery for severe damage to the knee ligaments or cartilage

    Iam 66 years old indian woman and never had knee problem .Only in past 6 months I have started to have knee pain in left knee . Some times the pain reaches below the knee spreading towards upper side and the lower side of the knee even when iam sitting down .i noticed that climbing stairs aggravates the pain .lying down does not help and I feel that the pain in the left also after the my center of the body – a depressingly new feeling in the middle of the body which I can not relate to knee pain . I have got the x- ray done and the doctors say that it is wear and tear of the age .it might have been the injury 2 years ago when I fell and hurt the knee .but since then , I also had a viral fever ‘chickengunya’- an Indian name of the fever which spread last year in Bangalore .The city in india I live .Presently iam in singapore and will returning to india on aug.10 . I saw your web site and thought that your advise might help me .

    Hi Dr. Yip,
    My left knee is hurting me after playing games of badminton and after resting for few days the pain seem lesser. Last month after the games my knee got the same problem and went to see my GP for some pain killers tablet and after one day it is okay, but the pain comes back after a while. Later try eating glucosamine and chrondotin and seem like the pain is still there. What causes it and let me know whether i can use my AIA insurance to cover and what is the cost. Let me have a appointment soon. I am now 57 old .
